Subject: [PATCH 3/3] drm/i915: Enable -Wsometimes-uninitialized
Date: Tue, 24 Aug 2021 15:54:27 -0700	[thread overview]
Message-ID: <20210824225427.2065517-4-nathan@kernel.org> (raw)
In-Reply-To: <20210824225427.2065517-1-nathan@kernel.org>

This warning helps catch uninitialized variables. It should have been
enabled at the same time as commit b2423184ac33 ("drm/i915: Enable
-Wuninitialized") but I did not realize they were disabled separately.
Enable it now that i915 is clean so that it stays that way.
